Simple Factory pattern

gistfile1.java

// The Factory
public final class VehicleFactory {
	
	// private constructor => can't be instanciated, final can't be extended since the constructor is not reachable for a subclass
	private VehicleFactory (){
		// no-op
	}
	
	public static Vehicel Vehicle produceVehicle(String name, String manufacturer, int horsepowerInPS){
		return new Vehicle(name, manufacturer, horsepowerInPS);
	}
}

public class Vehicle {

	private String name;
	private String manufacturer;
	private int horsepowerInPS;

	// package local constructor -> only the factory in the same package can create instances	
	Vehicle (String name, String manufacturer, int horsepowerInPS) {
		this.name = name;
		this.manufacturer = manufacturer;
		this.horsepowerInPS = horsepowerInPS;
	}

	public String getName(){
		return name;
	}
	
	public String getManufacturer(){
		return manufacturer;
	}
	
	public int getHorsepowerInPS(){
		return horsepowerInPS;
	}
	
	@Override
	public String toString() {
		return String.format(Locale.US, "Vehicle: %s %s (%d PS)", manufacturer, name, horsepowerInPS);	
	}
}	

// {...}
